Waiddaminute... The prequel was shounen ai, but this one isn't?

Can someone clarify whether this sequel is shounen ai as well? Because I for one am disappointed at the dropping of that genre... If it has actually been dropped, that is! If I want to read shounen ai, should I read this sequel?

I don't really understand why the tag was dropped either, but from what I have read up to (the latest), the amount of shounen-ai in both the stories stay pretty much the same so it doesn't really matter...
